PART 2 - PRODUCTS
2.1 MODES OF OPERATION
A. UPS shall be designed to operate as a double conversion, on-line reverse transfer system in the following modes.
1. Normal: The UPS system shall continuously supply power to the critical load. 2. Battery: Upon failure of the utility AC power source, the critical load shall be supplied by the
inverter, which, without any interruption, shall obtain its power from the battery. 3. Recharge: Upon restoration of the utility AC power source (prior to complete battery
discharge), the PFC rectifier shall power the inverter and simultaneously recharge the battery. 4. Static bypass: The static bypass switch shall be used to transfer the load to the bypass without
interruption to the critical power load. This shall be accomplished by turning the inverter off. Automatic re-transfer or forward transfer of the load shall be accomplished by turning the inverter on.
5. Maintenance bypass: In maintenance bypass the load is supplied with unconditioned power from the bypass input included in the UPS.
6. ECO mode: The UPS system is configured to use static bypass operation as the preferred mode under predefined. Transfers to battery operation upon utility failure. Efficiency up to 99%.
7. ECOnversion: ECOnversion allows the system to supply the active part of the load through the bypass. The inverter is kept running in parallel with the bypass source and supplies the
Page 20 of 27
reactive part of the load. The input power factor of the UPS is, regardless of the load power factor, maintained close to unity as the reactive part of load is significantly reduced in the UPS input current. In case if an interruption to the utility/mains supply, the inverter immediately maintains the output voltage so that breaks or drops during this transfer are practically eliminated. UPS operates with static bypass in parallel with main inverter. Main inverter actively corrects power factor, and harmonics to provide sinusoidal main input current without interruptions.
8. Parallel operation: The system shall have the option to install up to 3 UPSs in parallel for capacity and up to 3+1 for redundancy. a. The parallel UPSs shall be of the same design, kVA-size, voltage, and frequency. b. Output control: A load sharing circuit shall be incorporated into the parallel control circuits
to ensure that under no-load conditions, no circulating current exists between the UPSs. This feature also allows each UPS to share equal amounts of the total critical load bus. The output voltage, output frequency, output phase angle, and output impedance of each UPS shall operate in uniformity to ensure correct load sharing.
c. Parallel system control: The UPS shall have no single dedicated control system designed to control of the parallel system.
d. Communication: Communication between the UPSs shall be connected so that the removal of any single cable shall not jeopardize the integrity of the parallel communication system. Load sharing communications shall be galvanically isolated for purposes of fault tolerances between UPSs. A UPS’s influence over load sharing shall be inhibited in any mode where the UPS inverter is not supporting its output. Transfer to and from bypass can be initiated from any online UPS.
9. External synchronization: Synchronization of the output of the UPS with any other independent source for use with downstream transfer switches. The synchronization at the UPS is controlled from an input on the interface boards.
2.2 COMPONENT DESCRIPTION
A. PFC rectifier and battery charger: Incoming AC power shall be converted to a regulated DC output voltage by an IGBT (insulated gate bipolar transistor) power factor correction (PFC) rectifier. The PFC rectifier shall provide high quality DC power to charge the batteries and power the inverter and shall have the following characteristics: 1.

a. The inverter shall be electronically turned off to protect against overloads and abnormal load conditions which exceed the units rating.
b. UPS systems shall sense an overload condition and automatically transfer to the bypass input source which shall be used to provide the necessary current required.
6. Over-current Protection a. The inverter shall be protected from excessive overloads, including reverse currents, by fast
acting fuses to prevent damage to power semiconductors. All fuses shall be provided with a blown fuse indicator with alarm indication on the control panel.
C.
